摘要:
The present invention relates to the methods and compositions for the treatment of subjects having compromised bone conditions. Specifically, the invention relates to combinatorial therapeutic strategies including small molecules and peptide mimics of LIM mineralization proteins, particularly LMP-1, to overcome the dose-related translational barriers for BMP-2 therapeutics.

摘要:
Methods of expressing LIM mineralization protein in non-osseous mammalian cells, such as stem cells or intervertebral disc cells (e.g., cells of the annulus fibrosus, or cells of the nucleus pulposus) are described. The methods involve transfecting the cells with an isolated nucleic acid comprising a nucleotide sequence encoding a LIM mineralization protein operably linked to a promoter. Transfection may be accomplished ex vivo or in vivo by direct injection of virus or naked DNA, or by a nonviral vector such as a plasmid. Expression of the LIM mineralization protein can stimulate proteoglycan and/or collagen production in cells capable of producing proteoglycyan and/or collagen. Methods for treating disc disease associated with trauma or disc degeneration are also described.
摘要:
Methods of expressing LIM mineralization protein in mammalian cells are described. Methods of expressing LIM mineralization protein and assessing glycosylation of the LIM mineralization protein in prokaryotic and non-mammalian eukaryotic cells are also described. The methods involve transfecting the cells with an isolated nucleic acid comprising a nucleotide sequence encoding a LIM mineralization protein. Transfection may be accomplished in vitro, ex vivo or in vivo by direct injection of virus or naked DNA, or by a nonviral vector such as a plasmid.
摘要:
Methods of inducing the expression of a proteoglycan such as aggrecan in a cell are described. A method is described which includes transfecting a cell with an isolated nucleic acid comprising a nucleotide sequence encoding a LIM mineralization protein operably linked to a promoter. The LIM mineralization protein can be rLMP, hLMP-1, hLMP-1s, or hLMP-3. Transfection maybe accomplished ex vivo or in vivo by direct injection of virus or naked DNA, or by a nonviral vector such as a plasmid. The method can be used to induce proteoglycan synthesis in osseous cells or to stimulate proteoglycan and/or collagen production in cells capable of producing proteoglycan and/or collagen (e.g., intervertebral disc cells including cells of the nucleus pulposus and annulus fibrosus).

The invention provides methods and kits for treatment of pain or inflammation. In one embodiment, the kit comprises a biomembrane sealing agent, such as PEG, and a bioactive agent, such as a magnesium compound. The biomembrane sealing agent and/or the bioactive agent an intravenous administration, an intramuscular administration, an intrathecal administration, a subcutaneous administration, an epidural administration, a parenteral administration, an intra-articular administration, a direct application onto or adjacent to a site of the pathological condition, and any combinations thereof. Alternatively, the biomembrane sealing agent and/or the bioactive agent may be delivered from a pump or an implant.

摘要:
A bone marrow isolate rich in one or more connective tissue growth components, methods of forming the isolate, and methods of promoting connective tissue growth using the isolate are described. A biological sample comprising bone marrow is centrifuged to separate the sample into fractions including a fraction rich in connective tissue growth components. The fraction rich in connective tissue growth components is then isolated from the separated sample. The isolate can be used directly or combined with a carrier and implanted into a patient at a tissue (e.g., bone) defect site. The biological sample can comprise bone marrow and whole blood. The isolate can be modified (e.g., by transfection with a nucleic acid encoding an osteoinductive polypeptide operably linked to a promoter) prior to application to the tissue defect site. The isolate can be made and applied to the tissue defect site in a single procedure (i.e., intraoperatively).
摘要:
Effective treatments of acute pain for extended periods of time are provided. Through the administration of an effective amount of dexamethasone at or near a target site, one can relieve pain cause by diverse sources, including but not limited to spinal disc herniation (i.e. sciatica), spondilothesis, stenosis, discongenic back pain and joint pain as well as pain that is incidental to surgery. When appropriate formulations are provided within biodegradable polymers, this relief can be continued for at least twenty-five days. In some embodiments, the relief can be for at least fifty days, at least one hundred days, at least one hundred and thirty-five days or at least one hundred and eighty days.
